The Pima County, Arizona, Sheriff’s Department revealed on Tuesday that a new "ransom" note in the Nancy Guthrie disappearance is not credible.
The new development came one day after sheriff’s officials said the agency and the FBI’s task force working on the Guthrie investigation were recently made aware of the note and social media comments.

Authorities did not say who may have sent the note, but cautioned people against responding to such messages.
"Anyone who receives a text message or other communication related to Nancy Guthrie is encouraged to report it to law enforcement," the sheriff's office said.
Guthrie, 84, the mother of NBC "Today" anchor Savannah Guthrie, was last seen at her home on the evening of Jan. 31. Guthrie disappeared after FBI investigators said she was kidnapped from her home in Pima County, Arizona. Footage from a doorbell camera showed a masked man with a gun tampering with a camera around the time of her disappearance.
